Suppose you have a log line like this:
[2009.08.27-09:46:34] (INFO ) Log4J Log Level
Our logfile reader allows to set the date format to '['yyyy.MM.dd-hh:mm:ss']' to match the date part, but matching will fail on '(INFO )', as the matcher expects that the severity is surounded by space.
Log4JLogEntryProcessor.REGEX == "(.*) (TRACE|DEBUG|INFO|WARN|ERROR|FATAL) (.*)"
We should perhaps allow (via some %x expressions for users to completely compose their entry format )
